BOILER-CLEANER.

Specification of Letters Patent.

Patented Jan. 1, 1918.-

Application filed March 23, 1917. Serial No. 156,964.

To all whom it may concern:

Be it known that I, lViLLIAM G. Cnoss, a citizen of the United States, residing at ()lney, in the county of Young and State of Texas, have invented a new and useful Boiler-Cleaner, of which the following is a specification.

The present invention appertains to boiler cleaners, and aims to provide a novel and improved appliance of that nature operable for cleaning the sediment and precipitate from the bottom of the boiler, the present device being preferably assembled permanently with the boiler to be used at intervals.

It is the object of the invention to provide a boiler cleaner of the nature indicated, embodying novel features to enhance the utility and efficiency thereof.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein Figure 1 is a plan view of the cleaner as applied, portions being broken away.

Fig. 2 is a side elevation of the cleaner as applied, portions being broken away and shown in section.

Fig. 3 is a detail view of one of the cleaning heads, portions being shown in section.

In carrying out the invention, a tubular member 1 is screwed or otherwise fastened to one end of the boiler B, preferably at the rear end thereof, and is provided at one side with a cock 2. A pipe 3 is slidable through the tubular member 1, and a packing nut 4 is adapted to be threaded upon the outer end of the tubular member 1 for compressing packing about the pipe 3 to prevent leakage. A wrench 5 is suspended from the pipe 3 and can be readily applied to the nut 4 for tightening or loosening the same.

Connected to the inner end of the pipe 3 within the boiler is a pair of cleaning heads 6 and 7, which are of similar construction although they are not exactly alike. Each of the heads is of arcua'te contour to conform to the belly of the boiler, and is hollow, being provided upon its lower convexed surface with outstanding tufts of bristles 8, and the head has apertures 9 between the bristles. The bristles bear against thebottom or belly of the boiler. The innerend of the pipe 3 is connected to one side of the head 6 and the other side of said head is connected by an extension pipe 10 with the confronting side of the head 7, although if desired, the head 6 need not be provided with the apertures 9, in which event the pipe 3 can extend through the head 6 to be connected directly to the head 7.

Alongitudinal guide rod 11 is terminally connected to the ends or heads of the boiler B, as seen in Figs. 1 and 2, and the head 7 is provided at an intermediate point with an upstanding bifurcated post 12 engaging.

the rod 11, to guide said head and pipe 3 for longitudinal movement. A suitable spring 13 is seated Within the bifurcated portion 12 and presses upwardly against the rod 11' to depress the head 7 yieldably against the bottom of the boiler. The spring 13 is slidable along the rod 11 with the head 7.

A suitable guard is carried by the head 6 for collecting the larger particles of sediment, and as illustrated, this guard or shield V embodies a wireframe 1 1 connected to the ends of the head 6 and extending from said head 6 away from the head 7. A filler 15 of wire mesh or any other suitable material is secured to the frame 14 and is extended downwardly, as at 16, to the intermediate portion of the head 6. The free portion of the frame 1 1 has an eye or loop 17 slidably embracing the rod 11 to guide the frame 1 1 and head 6 for longitudinal movement.

The outer end of the pipe 3 which is closed, has attached thereto a suitable handle 18 for reciprocating said pipe, and the pipe is provided near its outer end with an extensible leg 19 having a wheel 20 at its lower end to run upon the floor and support the free end of the pipe in the proper line of movement.

A coupling 21 interposed in the pipe 3 outside of the boiler, has a branch 22 provided with a controlling valve 23, and a suitable pump 24, the details of which need not be considered, is mounted upon the pipe 3 and is operable for sucking water through said pipe from the boiler when there is no pressure in the boiler.

Ordinarily, the heads 6 and 7 are at that end of the boiler remote from the tubular member 1, and to clean out the boiler, the valve 23 is opened, when there is suitable pressure in the boiler, so that the water is forced under pressure through the cleaning heads into the pipe 3 and thence outwardly through the branch 22. The pipe 3 is then pulled out of the boiler by means of the handle or hand hold 18, thereby moving the heads 6 and 7 toward the opposite end of the boiler. The bristles will loosen the sediment and precipitates, and the smaller particles will be forced with the water through the apertures 9 into and through the pipe 3. The larger particles are brushed ahead with the head 6, and are collected under and in front of the guard or shield, which carries the larger particles and foreign matter to that end of the boiler to which the member 1 is applied, and at which end of the boiler, the ordinary flow off cock (not illustrated) is disposed. Thus, the sediment which is not blown out through the pipe 3 is carried with the head 6 and its guard or shield to a point near the ordinaryflow off cock, whereby said accumulated matter can be blown out or removed. After the cleaning operation, the parts can be returned to normal position, and the pipe 3 can be reciprocated during the cleaning operation if necessary or desirable. WVhen there is no pressure in the boiler, the Valve 23 is left closed, and the pump 24 is operated to suck the water from the boiler through the pipe 8, whereby the smaller particles will be sucked into the pipe 3 to remove them from the boiler, instead of the particles being forced out under pressure from within the boiler.

Copies of this patent may be obtained for five cents each, by addressing the Having thus described the invention, what is claimed as new is 1. The combination with a boiler, of a pipe slidable through one end thereof, a longitudinal rod mounted within the boiler, an apertured cleaning head connected to said pipe and movable along the bottom of the boiler, said' head slidably engaging said rod, and spring means between said rod and head for depressing the latter.

2. The combination with a boiler, of pipe slidable through one end thereof, a longitudinal rod mounted within the boiler, an apertured cleaning head connected to the pipe and movable along the bottom of the boiler, bristles carried by said head to bear against the bottom of the boiler, said head slidably engaging said rod, and spring means between the rod and head for depressing the latter.

3. The combination with a boiler, of a member slidable through one end thereof, a longitudinal rod mounted within the boiler, a cleaning head connected to said member and movable along the bottom of the boiler, bristles carried by said head to engage the bottom of the boiler, and a guard carried by said head and projecting in one direction therefrom, said guard having means at its free end slidably engaging said rod.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
